The Syloxi hairspring is the key part. Silicon is not affected by magnetic fields and is far less sensitive to temperature changes than a metal alloy, and the patented shape of the spring keeps the watch running at a steady rate whatever position it sits in. In 2026 Rolex also added resistance to magnetism, reliability and sustainability to the criteria of its Superlative Chronometer certification, which comes with a five-year international guarantee.

The gold models arrived in 2026, the centenary of the Oyster case. On their stone lacquer dials, the hour markers at three, six and nine o’clock are cut from natural stone, a first for Rolex: heliotrope on the green dial of the 28 in yellow gold, dumortierite on the blue dial of the 34 in Everose gold. Their cases and bracelets are mostly satin-finished, with a polished domed bezel. The RBR versions swap the stones for diamonds, on the bezel as well as on the dial.
Calibre 2232 Compared with the 3230 and the 2236
Rolex splits the Oyster Perpetual between two movements. The larger Oyster Perpetual 36 and Oyster Perpetual 41 use calibre 3230, with a blue Parachrom hairspring and about 70 hours of power reserve. The 2232 is the smaller movement for the 28, the 31 and the 34, with about 55 hours.
Its closest relative is calibre 2236, which powers the 28 mm Lady-Datejust. It shares the Syloxi hairspring, the Paraflex shock absorbers and the 55-hour reserve, and adds an instantaneous date with rapid setting. If you want a small Rolex without a date, the 2232 is the movement; if you want the date, look at the 2236.
The 2232 replaced two older calibres in 2020: calibre 2231 in the 26 mm 176200 and the 31 mm 177200, and calibre 3130 in the 34 mm 114200. The relaunch also grew the smallest Oyster Perpetual from 26 mm to 28 mm.
